Abstract (en)
[origin: EP3299881A1] A light modulation film (1) includes a light modulation layer (30) whose state is reversibly changed between a transparent state by hydrogenation and a reflective state by dehydrogenation, and a catalyst layer (40) that promotes hydrogenation and dehydrogenation in the light modulation layer, in this order on a polymer film substrate (10). In a thickness-direction distribution of an element concentration as measured by X-ray electron spectroscopy, the light modulation layer (30) includes a light modulation region (32) with an oxygen content of 50 atom% or more and having a thickness of 10 nm or more on a catalyst layer (40)-side, and an oxidized region (31) with an oxygen content of less than 50 atom% on a polymer film substrate (10)-side.
